MECHANICAL BAR- CHART.

Application filed October 23, 1924. Serial No. 745,471.

To all whom t may concern:

'lle it known that' l, lllinmne. J. STRATTON, a citizen oit the United States, residing at wi-fallace, in the county of Shoshone, inthe State oi Idaho, have invented a new and' useful Mechanical Bar Chart of which the following' is a specihcation.

The invention relates to the art ot pre paring exhibits in graphic chart form and generally resides in the provision of a mechanical bar chart for that purpose. i ln the art ot preparing such exhibit many dii'l'erent forms of charts are used and whereupon the fluctuations of value, quantity ot production, or otherI desired statistics are graphically exhibited by curves, circles, point to point lines, bars or otherwise according to the knowledge and whims of the individual whose duty it is to prepare such charts.

The most simple form of such chart, for ordinary business purposes, is the common bar chart wherein the fluctuation is graphically illustrated by value or quantity indieating lines drawn to the length desired to indicate the particular value or amount. 1With this form ot chart the present invention is concerned.

In preparing the common type ot exhibit in graphic chart form, a scale is arrived at that will take in the minimum and maximum ot the values or quantities to be depicted by the exhibit, lines are then ruled to tit iaichscale, and, in case ot the bar type of chart, the bars are then drawn to the lengths necessary to indicate the desired value or quantity. This is very slow and tedious work and must be done with great care, or the exhibit will not only be incorrect but will look very unattractive. Obviously such work cannot be done with the necessary degree oi accuracy or neagness unless trie party skilled vas a drattsman, thus making the preparations of such exhibits an expensive system, due to the time consumed and the duplication ot employees made necessary by the present methods of preparing such charts.

Therefore, it is the object of this invention to provide a mechanical bar chart which is capable ot being used and of being prepared for use as a graphic exhibit of quantities or values without the necessity ot any lines whatever being drawn by the individual or individuals preparing or compiling the said chart.

It is a` Yfurther object of the invention to provide a chart ot the character stated which is so simple of construction and of operation that it may be used by anyone, whether he has skill as a drattsman or not, thus eliminating the necessity of employing high priced employees and making it possible for the party having charge of collecting kand recording suoli data to prepare the charts himself with the result of time saving and also the elimination of many possibilities of error.

More specifically it is the object of the present invention to provide another embodiment oi the generic invention disclosed in my application filed November 22, 1923,

Serial No. 676,450, an embodiment in which the individual bar units are arranged permanently in a folder or on a suitable backing in such a way as to produce a permanent record that can be filed away as a complete unit and eliminate danger of disarranging the units of the record.

In its general nature the present invention comprises a structure in which is pasted or otherwise suitably secured a seriesl of individual bar units, arranged side by side with their horizontal lines and spaces in register, each unit comprising column-like sections, at least one of which has an indicating bar extending substantially its `full length, the sections being adapted for separation, the section or sections having the bars' being adapted to be cut oil or shortened to accord with the bar-value desired; the unit section having no har is the one pasted to the backing in such manner that a bar section of one unit will over-lie the secured section of the next unit at times, the barfsect-ions being` Jfoldable back upon the respective secured section to expose the bars at other times and beingl adapted to be pasted or otherwise secured to the secured section with the bar exposed when desired.

More subordinately the invention also resides in those novel 'teaturesot construction, combination and arrangement of parts, all ot' which will be iirst fully described and then be specifically pointed out in the appended claims, reference being had to the accompanying' drawings, in which:

Figure l is a perspective view of one embodiment of my invention before the chart has been used.

Figure 2 is a tace View of the invention with the chart made up.

and income curves tor the desired interval. et time tor which the chart is made up.

instead oi, having the har sections unitetL on vertical Afolding lines as shown in Figures l to l() inclusive, theyr may he united on a horizontal line l5 as shown in Figures ll and l2 for example. ln this ligure 16 represents the section oit the unit which is pasted or secured to the tolder and lf2' the section ot the unit which is adapted to he torn oi'i or severed to indicate the har value, .i8 designating the indicator har ot the particular unit.

Other modifications ot the invention may he made without departing 'troni the spirit oif the invention or the scope olf the appended claims.

.iii-om the toregoing description, taken in connection with the accompanying dran'- ings, it is thought the construction, operation uses and advantages ot my invention will be readily understood by those skilled in the artlVhat l claim is:

l. ln har charts, a hacking, a plurality ol strip units each having horizontal divisions at like. points on their front and hack faces, each said units comprising two sections toldalole over on a longitudinal separation line tace' to tace, one tace oi the unit having an indicating har on one ol' its sections and having the corresponding tace ot its other section secured to the hacking, the har-face section ot' a unit adapted to overlie the secured section ot the nent adjacent unit during inoperative position to hide the har from view.

2. in har charts, a hacking, a plurali@ oi' strip units each having horizontal divisions at like points on their iront and hack taces, reach said units comprisino' two sections ioldahle over on a longtucinal separation line tace to tace, one tace oil the unit having an indicating har on one oit its sections and having the corresponding tace oit its other section secured to the hacking, the har-tace section ot a unit adapted to overlie the secured section off the next adjacent nnit during inoperative position .to hide the har trom view, the har it'ace section oi" a unit being adapted to he :folded hack over its respective secured section to expose the har during operative position and adapted to he horizontally severed to regulate the length ot the indicating har.

f3. ln har charts, a, liaeking, a plurality oi strip units each having horizontal divisions at like points on their front and hack laces, each said units comprising` two sections folded over on a longitudinal separation line, one of said sections having an indicatinghar on one tace, the corresponding face of the other section being secured to the hacking, the section having the indicating har adapted to he folded over onto the secured section to espose the indicating` har and adapted to he horizontally severed to regulate the length the indicating har., and means securing the ren'iaining portion ot the har section to its respective secured section to permanently e pose the har. K

l. ln har charts, a hacking, a plurality ot strip units each having horizontal divisions at like points on their iront and hach itaces, each said units comprising two sections folded over on a longitudinal separation line, one of said sections having` an indicating har on one tace, he corresponding tace of the other section heing secured to the hacking, the section having the indicating har adapted to he Aliolded over onto the secured section to expose the indicating har and adapted to he horizontallyr severed to regulate the length oi the indicating har, means securing the remaining portion ot the har section to its respective secured section to permanently expose the har, said har section of the units having vertical column-lines paralleling the hars and adapted when the har section is secured in the permanent position to register with the line ot separation of the adjacent section and constitute column dividers.
